Ok some of these Mafia Wars pages have the option to donate and get "Pimped" it's like 15 bucks or so for one of the ones and they have 600k fans. So when they post you and your link you are getting a bunch of adds all at once. Maybe if you talked to some you could get them to post your page instead. But essentially this instead of paying for someone to send 1k of their friends to your page, where you aren't even guaranteed they are doing it. You could do this a few times or convince them to do the page and either have a few accounts with 5k fans each or maybe have a page that is getting 600k possible views.
